The 6 Most Popular Types of Information Systems!

📌What are Information Systems?
Information systems are collections of multiple information resources to gather, process, store, and disseminate information.
Tools such as laptops, databases, networks, and smartphones are examples of information systems. So yes, as you read this article, you’re employing an information system! Many people rely on various types of information systems to communicate with friends and family, bank or shop online, or look up information via a search engine.
Companies and organizations employ information systems to communicate and work with their customers and suppliers, manage the organization, perform essential business operations, and roll out and maintain marketing campaigns.
📌Six Major Types of Information Systems.
Now that we have dealt with the basics, let's look at the six primary types of information systems. Although information systems are not limited to this list, typical businesses and organizations have the following six, each system supporting a different organization.
✅Transaction Processing System (TPS):
Transaction processing is essential to helping businesses perform daily operations. Transactions are defined as any activity or event that affects the company, and include things like deposits, withdrawals, shipping, billing customers, order entry, and placing orders. TPS supports these business transactions.
✅Office Automation System (OAS):
OAS consists of computers, communication-related technology, and the personnel assigned to perform the official tasks. The OAS covers office transactions and supports official activity at every level in the organization. The official activities are subdivided into managerial and clerical activities.
Office automation systems include the following applications:
1️⃣Email: The email application also covers file attachments such as audio, video, and documents.
2️⃣Voice Mail: This application records and stores phone messages into the system’s memory and can be retrieved anytime.
3️⃣Word Processing: Word processing covers the creation of documents, including memos, reports, letters, and anything else that’s printable electronically. The created text can be copied, edited, and stored via word processing commands, and checked for grammar and spelling, line and word counting, and headers and footers.
✅Knowledge Work System (KWS):
The KWS is a specialized system that expedites knowledge creation and ensures that the business's technical skills and knowledge are correctly applied. The Knowledge Work System aids workers in creating and disseminating new information using graphics, communication, and document management tools. Here are some examples of KWS:
1️⃣Computer-Aided Design Systems (CAD): CAD systems automate design creation and revision via computers and graphics software, especially in the manufacturing and tooling processes.
2️⃣Financial Workstations: These systems pull and combine data from many different internal and external sources, covering research reports, market data, and management data. Financial workstations can rapidly analyze huge amounts of financial data and trading situations.
3️⃣Virtual Reality Systems: These systems take the CAD system to the next level, using interactive graphics utilities to create realistic computer-generated simulations. VR systems are typically found in scientific, educational, and business circles.
✅Management Information System (MIS):
Middle managers handle much of the administrative chores for day-to-day routines and performance monitoring, ensuring that all the work is aligned with the organization's needs. That's why MIS is such a valuable tool. Management Information Systems are specially designed to help middle managers and supervisors make decisions, plan, and control the workflow. The MIS pulls transactional data from various Transactional Processing Systems, compiles the information, and presents it in reports and displays.
Additionally, these reports can be produced monthly, quarterly, or annually, although MIS can have more immediate reports (e.g., hourly, daily).
✅Decision Support System (DSS):
The DSS is a management-level, interactive computer-based information system that helps managers to make decisions. The Decision Support System specifically gives middle managers the information necessary to make informed, intelligent decisions.
Decision Support Systems use different decision models to analyze or summarize large pieces of data into an easy-to-use form that makes it easier for managers to compare and analyze information. Often, these summaries come in the form of charts and tables.
✅Executive Support System (ESS):
The ESS is like the MIS but for executive-level decision-making.  The decisions involve company-wide matters, so the stakes are higher. Consequently, they demand more insight and judgment.
The ESS provides greater telecommunication, better computing capabilities, and more efficient display options than the DSS. Executives use ESS to make effective decisions through summarized internal data taken from DSS and MIS and external sources. In addition, executive support systems help monitor performances, track competitors, spot opportunities, and forecast future trends.
